Registration of a civil partnership concluded abroad
For a civil partnership registered abroad, the partners may, if they wish, be recognised as partners in Luxembourg by addressing a request to the Public Prosecutor's Office in order to register their partnership at the Luxembourg Civil Register.
Registration of a partnership registered abroad in the Luxembourg Civil Register allows the partnership to be considered as a Luxembourg partnership.
The registration of the partner in the RNPP is done after registration in the Civil Register.
